Abstract

本实用新型公开了一种膝关节假体胫骨平台,包括平台本体及其下侧的基座,所述的基座与胫骨通过骨水泥结合,而所述的平台本体与基座的接合处具有侧筋,所述的平台本体侧壁具有卡槽,所述的基座与胫骨具有3°的内翻角度。本实用新型的侧筋不仅能够使假体与骨水泥增加接触面积,而且能够实现在胫骨中的防旋;卡槽能够保证衬垫假体稳固结合;基座与胫骨有3°的内翻角度,实现关节面水平的同事满足人体生理角度,能够有效减小假体关节面的磨损。

Description

膝关节假体胫骨平台
技术领域
本实用新型属于骨科医疗器械领域,具体涉及一种初次植入人体的膝关节假体。
背景技术
目前,全膝关节置换术已经成为缓解膝关节炎、类风湿关节炎等导致膝关节严重损伤的一种有效治疗手段。现有的人工关节虽然能够达到稳定关节,缓解疼痛,实现基本生活自理的目的。但是由于设计结构角度不够贴合人体生理弯曲角度,动态情况下加速假体间的磨损。即使短期内无手术并发症,但是严重影响假体的使用寿命。
发明内容
本实用新型为解决现有技术存在的问题而提出,其目的是提供一种磨损小,符合人体生理角度的膝关节假体胫骨平台。
本实用新型的技术方案是:
一种膝关节假体胫骨平台,包括平台本体及其下侧的基座,所述的基座与胫骨通过骨水泥结合,而所述的平台本体与基座的接合处具有侧筋,所述的平台本体侧壁具有卡槽,所述的基座与胫骨具有3°的内翻角度。
本实用新型的侧筋不仅能够使假体与骨水泥增加接触面积,而且能够实现在胫骨中的防旋;卡槽能够保证衬垫假体稳固结合;基座与胫骨有3°的内翻角度,实现关节面水平的同事满足人体生理角度,能够有效减小假体关节面的磨损。
附图说明
图1 是本实用新型的示意图;
图2 是本实用新型的基座倾斜角度图;
其中:
1 平台本体 2 基座
3 侧筋 4 侧壁
5 卡槽。
具体实施方式
以下,参照附图和实施例对本实用新型进行详细说明:
如图1~2所示,一种膝关节假体胫骨平台,包括平台本体1及其下侧的基座2,所述的基座2与胫骨(未示出)通过骨水泥结合,而所述的平台本体1与基座2的接合处具有侧筋3,所述的平台本体1侧壁4具有卡槽5,所述的基座1与胫骨(未示出)具有3°的内翻角度。
所述的侧筋3为3条。
所述的卡槽5设置在平台本体1的前后侧壁4。
胫骨关节面有3°内翻,因胫骨切面与胫骨机械轴垂直,为获得屈膝间隙,要求股骨髁有3°外旋,实际使用中胫骨平台1后倾定位,胫骨导向杆与胫骨前脊平行,依据病人解剖不同改变切骨精确水平,后倾3°-5°进行截骨,假体旋转对线,假体前缘中央对准胫骨结节内侧1/3处,以较小损害侧平台为准则,建议切骨8mm或10mm,之后使用胫骨对线器对线,如需要,通过滑动胫骨对线器远侧部分至适当位置纠正内外翻。
本实用新型的侧筋不仅能够使假体与骨水泥增加接触面积,而且能够实现在胫骨中的防旋;卡槽能够保证衬垫假体稳固结合;基座与胫骨有3°的内翻角度,实现关节面水平的同事满足人体生理角度,能够有效减小假体关节面的磨损。
